Okay, that changes things, but I do think that 8 ohms between PCM C4 P1 and TCM H is kind of high. Not sure which measurement falls into this, but if you have the SKREEM and PCM plugged in, you should measure ~60 ohms between the H and L pins on the unplugged TCM connector. If only the SKREEM or the PCM is plugged in, you should measure around ~120 ohms between the H and L pins on the unplugged TCM connector. (Negative Battery cable off, key out of the ignition.) Since you have the SKREEM out, measure between pins 1 and 2 on the module - it should read ~120 ohms. Also, since you have the TCM out, have you noticed any transmission fluid around the TCM or in the TCM module connector? (use a white cloth/tissue and wipe around there). Sometimes, which I think is pretty insane, the transmission connector leaks, and the fluid wicks up the cable to the module, shorting out the module.

I think all those measurements were in my list already including skreem 1-2, however Im gonna remeasure them all tonight if I get time now that all 3 modules are unplugged and see what I find. The help youve provided so far is immensely appreciated, it wouldve taken me so long just to get to the point Im at now! So thanks for that!! Hopefully I cant find whats causing the bad measurements and get access to it, Id love to not need to take apart my center console and everything else to get to the SLA but will if I have to.
